DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film-adhered printed matter and a method for producing the same, and more particularly to a film-adhered printed matter having an uneven mesh pattern only on its surface and no irregularities on its back surface. .

[0002]

2. Description of the Related Art Conventionally, embossed sheets obtained by forming an uneven mesh pattern on a sheet of paper, a film made of a polymer material, a leather, etc. have been used for printing, wrapping paper,
It is used in the fields such as stationery, calendar, wallpaper material, and surface layer of decorative plywood. For example, in the case of a printed matter, a film or the like is stuck to the printed matter, and after the lamination, the adhesive is left for a predetermined time until the adhesive is dried and solidified, and then the surface of the laminated printed matter such as an uneven mesh pattern is formed. Embossing has been used to apply a pattern to increase the gloss and binding effect of the printed matter surface.

[0003]

However, the printed matter obtained by the above-mentioned conventional processing method is, as is apparent from FIG. 1, in which the lower right portion of the printed matter is turned over so that the appearance of the front and back sides can be observed. An uneven shape (pattern pattern in the figure) is generated on the front surface A, and an uneven shape (pattern pattern in the figure) corresponding to this shape is generated on the back surface B. For this reason, when performing the above-mentioned conventional surface processing and embossing on the front cover and back cover of books, magazines, etc., particularly when performing the surface processing and embossing on double-sided printed matter However, there is a problem that the printed surface of the back surface is damaged, which is not preferable from the viewpoint of aesthetics. That is, in processing such a printed material, a film in which an adhesive such as a synthetic resin is previously applied to the surface of the printed material is subjected to pressure bonding by a laminating method, and then the printed material is subjected to an engraving roll (mesh roll) and a receiving roll (rubber roll or (A paper roll or the like) to give the printed matter an uneven pattern. Therefore, there is a problem that an uneven shape corresponding to the uneven shape of the surface appears on the back surface of the printed matter.

Further, the above-mentioned conventional surface processing method has a problem that poor adhesion between the film and the printed matter is liable to occur, and it is necessary to allow time for the synthetic resin adhesive to be completely cured after laminating. was there.

The present invention has been made to solve the above-mentioned conventional problems, and is directed to a film-adhered printed material having a surface provided with an uneven mesh pattern and a surface having no unevenness, wherein Has good adhesion,
It is an object of the present invention to provide a film-adhered printed material and a method for manufacturing the same, in which the time of the manufacturing process is reduced.

[0006]

According to the present invention, there is provided a method for producing a film-adhered printed material, comprising the steps of: forming a biaxially stretched synthetic resin film on an engraving roll heated to a temperature from room temperature to a temperature at which the film does not curl. Embossed by feeding between a receiving roll (rubber roll or paper roll, etc.)
An embossed film is obtained, and the obtained embossed film and printed matter are adhered to each other with a predetermined pressure using an adhesive, and a surface (preferably a glossy surface) provided with an uneven mesh pattern and an uneven shape are formed. And to obtain a film-adhered printed matter having a surface having no surface. The thickness of the biaxially stretched synthetic resin film used as a raw material is preferably 15 to 50 μm, and the embossing is performed at room temperature (about 20 ° C.) to 15 μm.
It is preferably performed at a temperature of 0 ° C., and the distance between the convex portion and the concave portion of the concave and convex shape of the mesh pattern of the embossed film is 50.
μm or less, and an adhesive is applied to one or both of the embossed film and the printed matter (preferably to the embossed film) based on the surface area of the printed matter.
After coating in an amount of 5 to 5.0 g / m ^2, the film is preferably stuck to the printed surface of a printed material. More preferably, the embossing is performed at 40 to 120 ° C., and the amount of the adhesive applied is 3.0 to 4.0 g / m ² based on the surface area of the printed material.

[0007] Further, the film-attached printed material of the present invention is obtained by embossing a biaxially stretched synthetic resin film using an engraving roll and a receiving roll heated to room temperature to 150 ° C, and a printed material using an adhesive. The surface on which the irregular mesh pattern is applied (preferably a glossy surface)
And a surface without irregularities.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the biaxially stretched synthetic resin film used in the present invention include biaxially stretched films obtained from polyesters such as polypropylene and polyethylene terephthalate, and vinyl chloride. Specifically, for example, Trefan. There are films commercially available as BO or Lumirror (trade name, manufactured by Toray Industries, Inc.). If the film thickness is less than 15 μm, the desired concavo-convex pattern will not appear even when embossing, and if it exceeds 50 μm, the desired concavo-convex pattern will appear, but it will not be economically attractive in terms of the cost of the film.

If the heating temperature of the film when embossing such a film is lower than room temperature, a beautiful emboss cannot be obtained, and if the temperature exceeds 150 ° C., shrinkage (shrinkage) or wrinkles of the film width occurs. There's a problem.

When the distance between the convex and concave portions of the embossed film of the embossed film exceeds 50 μm, the film strength is reduced. The lower limit is not particularly limited, and may be any range as long as the unevenness of the mesh pattern is observed.

The adhesive that can be used in the present invention is not particularly limited, and any adhesive can be used as long as the film and the printed matter can be satisfactorily bonded. For example, acrylic,
Acrylic-urethane, vinyl chloride, vinyl acetate,
An adhesive such as an epoxy-based adhesive can be used. In the present invention, since the film itself has an uneven mesh pattern, the film and the printed matter are bonded by line bonding instead of surface bonding. That is, as shown in FIG. 4B, the adhesive 7 is applied to the concave portion 9 on the side of the embossed film 8 which is in contact with the uneven printed material 6 and the edge portion (convex portion) of the convex portion 10 located away from the printed material. And at least a portion of the inner wall portion). For this reason, the amount of the adhesive is preferably in the above range. If the amount of the adhesive is less than 1.5 g / m ^{2 on the} basis of the surface area of the printed material to be surface-processed, there is a disadvantage that poor adhesion between the embossed film and the printed material occurs, and 5.0 g / m ^2.
If it exceeds m ² , a large amount of the adhesive will penetrate into the concave portions 9 of the embossed film and adhere to it in a supersaturated manner. As a result, there is a problem that the mesh pattern, particularly the edge portion thereof, is difficult to come out sharply.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in more detail with reference to the drawings, but these examples are merely illustrative.
It does not limit the invention. (Example 1) As shown in FIG. 2, a male type engraving roll (mesh roll) 1 and a female type paper roll 2 were used, and the paper roll was wetted with water as a pretreatment for embossing. The embossed shape of the engraving roll was transferred. The embossing depth d of this engraving roll is up to 50
μm. Next, a thickness of 30 μm and a width of 1500 m /
m of biaxially stretched polypropylene film (trade name: Trefan. BO, manufactured by Toray Industries, Inc.) 3 at a feed rate of 50
m, the paper was supplied from the direction of the arrow between the engraving roll 1 and the paper roll 2 heated to a temperature of 120 ° C. under a predetermined pressure, and embossing was performed by the rotation of the engraving roll and the following rotation of the paper roll (FIG. 3). The uneven mesh pattern of the embossed film 8 sent out has a height d.
Was 50 μm or less. The obtained embossed film was wound up on a roll. Next, this embossed film was stuck on the printing surface of the printed matter. That is, as shown in FIG. 4, between the hot roll 4 and the impression cylinder 5, 3-4 g of the printed matter 6 and the acrylic adhesive (trade name: D-Tight 6920, manufactured by Dainippon Ink and Chemicals, Inc.) 7 / M ^{2 is} applied in the direction of the arrow, and by applying a rotation of these rolls and the drum under a predetermined pressure (for example, 150 kg / m ² or more), a sticking step is performed. A printed product was obtained. As shown in FIG. 5, the resulting film-attached printed matter has a beautiful mesh pattern on the surface X on the film side, and unlike the case of FIG. No mesh pattern appeared. The embossing feeling on the surface was good, and the embossing feeling of the mesh pattern was particularly sharp.

[0013]

According to the method for producing a film-attached printed matter of the present invention, the obtained film-attached printed matter has an uneven mesh pattern only on the surface of the printed matter, and no mesh pattern appears on the back surface. Therefore, the appearance of the back surface is not impaired, and especially in the case of a double-sided printed material, the printed surface of the back surface is not stained. Furthermore, since the adhesion between the film and the printed matter is good and there is no need to wait for the time after the application of the adhesive, the time for the manufacturing process can be shortened.
